Not Just a Black Box: Finding What Matters Inside Neural Networks
Neural networks often feel like a closed door, but a new way peeks inside and shows what parts really matter.
The idea is simple: look at what each part does compared to a normal or quiet state, and see how much it changed.
That lets the method point out the important features that drove a decision, so the model stop being a mysterious black box.
It's fast enough to use on pictures and on DNA data, so researchers can see clear signals in both faces and genes.
Instead of looking only at tiny slopes or guesses, this approach compares change from a baseline and gives credit where it's due — producing easy to read contribution scores.
The trick is checking a part's activity against a reference activation, then tracing influence back through the network.
Users get explanations that feel honest and useful, the results were clearer than some older ways.
If you want to trust a model, seeing why it chose something makes all the difference, and this method helps do that.
